Description

Sheet material supply device

The present invention relates to a sheet material supply device that supplies and arranges a sheet material on the surface side of the glass plate in order to alternately laminate glass plates and sheet materials on a pallet.

As is well known, there is a case where a glass plate is vertically stacked on a pallet for transportation and storage of the glass plate. In this case, a sheet material as a cushioning material or a spacer is interposed between the glass plates for the purpose of preventing the occurrence of scratches due to direct contact between the glass plates and preventing damage to the glass plates during transportation. . Therefore, the glass plate laminated body which arranges a glass plate and a sheet material alternately is formed on a pallet.

And, on the pallet, the work of arranging the sheet material so as to overlap the surface side (exposed surface side) of the glass plate is limited in that it can be done manually, so a dedicated device is usually used. It is.

In Patent Document 1, a strip-shaped sheet base material is pulled out from a base material roll, and both ends in the width direction of the sheet base material are cut by holding means, and then the sheet material after cutting is tensioned by the holding means. There is disclosed a sheet material supply device that holds the sheet material in an applied state and arranges the held sheet material on the surface side of a glass plate placed vertically on a pallet.

JP 2012-35988 A

However, in Patent Document 1, since the support member that supports the sheet material holding means extends from the floor surface on which the pallet or the like is placed, the space occupied by the floor surface of the sheet material supply device is inevitably required. It gets bigger.

In particular, when dealing with packaging of glass plates of various sizes, a dedicated sheet material supply device corresponding to each of the sheet materials having different widths must be individually installed, and the occupied space on the floor surface is reduced. The increase becomes significant.

In view of the above circumstances, an object of the present invention is to provide a sheet material supply device capable of reducing the occupied space on the floor surface as much as possible.

The present invention devised to solve the above problems is to feed a belt-like sheet base material in order to form a glass plate laminate in which glass plates and sheet materials are alternately laminated in a vertical posture on a pallet. A sheet material supply apparatus configured to cut a fixed length at a cutting position, move the cut sheet material to a supply position, and dispose the sheet material on the surface side of the glass plate, both ends of the sheet material in the width direction Each of the pair of holding means, and a pair of guide members that movably support each of the pair of holding means between the cutting position and the supply position. Suspended and supported by a fixed system above the pallet.

According to such a configuration, the holding means for holding the sheet material is supported by the guide member that is suspended and supported by the fixed system above the pallet. In this state, if the holding means is reciprocated between the cutting position and the supply position, the sheet material can be supplied and arranged on the surface of the glass plate on the pallet. Therefore, since the sheet material can be supplied in a state where the guide member and the holding means are separated from the floor surface, the occupied area of the floor surface can be reduced.

In the above configuration, it is preferable that the fixed system is a building structure positioned above the pallet.

In this way, it is possible to effectively use building structures such as ceilings and beams that tend to be dead spaces. Moreover, since the structure of a building is robust, it is suitable as a fixed system.

In the above configuration, it is preferable that at least one of the pair of guide members is movable in the width direction with respect to the fixed system.

In this way, various types of sheet materials having different widths can be handled by the same sheet material supply device. Therefore, it is not necessary to separately provide a dedicated sheet material supply device corresponding to the width of the sheet material, so that the floor space can be further saved.

In the above configuration, it is preferable that each guide member is movable in the front-rear direction with respect to the fixed system.

In this way, the front-rear position of the holding means can be adjusted by moving the guide member in the front-rear direction. Therefore, even if the lamination position of the frontmost glass plate changes due to the progress of the alternate arrangement of the vertically placed glass plate and the sheet material, the positional relationship between the glass plate and the holding means is always kept constant. Can do. Therefore, it is possible to continue supplying a stable sheet material to the surface of the glass plate existing on the forefront side.

In the above configuration, a plurality of pairs of the holding means and the guide member are provided in the width direction, and the plurality of sheet materials are supplied to different positions of the single pallet or to the plurality of pallets. It may be.

In this way, a plurality of sheet materials can be supplied and arranged at the same time.

In the above configuration, an auxiliary guide member that is movable in the vertical direction along each guide member may be provided, and the holding means may be provided so as to be movable in the front-rear direction along the auxiliary guide member.

In this way, by moving the holding means in the front-rear direction along the auxiliary guide member, the position in the front-rear direction of each holding means is finely adjusted in accordance with the distortion of the pallet and the number of laminated glass plate bodies. Therefore, accurate sheet material supply can be realized. In this case, since the holding means is supported by the guide member via the auxiliary guide member, the vertical movement of the holding means can be realized by moving the auxiliary guide member in the vertical direction along the guide member.

As described above, according to the present invention, the guide member that supports the holding means that holds the sheet material is suspended and supported by the fixing system above the pallet. Can be reduced.

The direction (indicated by arrow B in the figure) is inclined so that the upper side is shifted to the rear side (back side) with respect to the vertical direction so as to be parallel.

The size and material of the glass plate 17 and the sheet material 4 are not particularly limited, but for example, the following can be used. That is, the glass plate 17 has a length of each side of 1 m or more and a thickness of 0.5 to 3.0 mm. The sheet material 4 has a length of four sides of 1.05 m or more and a thickness of 0.05 to 2.00 mm, and the width direction both ends and the upper side of the sheet material 4 protrude from the glass plate 17. . As the sheet material 4, a foamed resin sheet made of stretchable polyethylene or the like, paper, or the like is used.

Next, the operation of the sheet material supply apparatus having the above configuration will be described. 4 to 7 to be referred to in the following description, the guide member 12 and the drive mechanism of each holding means 5 and 6 are not shown for convenience, but the omitted parts are also shown in FIGS. Consider the symbols shown in.

First, in the initial stage before cutting out the sheet material 4 from the strip-shaped sheet base material 1, as shown in FIG. 4, a pair of lower end holding means 6 is disposed immediately below the pair of upper end holding means 5, All of the clamping

mechanisms

5a and 6a of the holding means 5 and 6 are in an open state.

From this state, as shown in FIG. 5, when the feeding nip roll 10 feeds the strip sheet base material 1 downward and the lower end of the strip sheet base material 1 passes through the pair of lower end holding means 6, the feed nip roll 1 10 is temporarily stopped. At the time of this stop, the clamp mechanism 6a of the pair of lower end holding means 6 is closed, and the both ends in the width direction at the lower end of the belt-like sheet base material 1 are sandwiched and held.

FIG. That is, the holding means 5 and 6 reciprocate between the cutting position where the cutting means 3 is disposed and the lower moving end which is the supply position of the sheet material 4.

In this case, when the sheet material 4 is moved downward, the surface of the glass plate 17 and the sheet material 4 are prevented from coming into contact with each other to prevent the surface of the glass plate 17 from being stained or damaged. After the sheet material 4 reaches the lower moving end, the second base portion 15 is moved in the front-rear direction, and the sheet material 4 is brought into contact with the surface of the glass plate 17, whereby the air between the both 4 and 17 is removed. Is done.

Under this state, the subsequent glass plate 17 is arranged (laminated) on the surface side of the sheet material 4 by a glass plate conveying means (not shown), and the sheet material 4 is pressed by the weight of the glass plate 17. At that time, the holding means 5 and 6 and the

clamp mechanisms

5a and 6a are opened.

Thereafter, the holding means 5 and 6 are moved up to return to the initial vertical position. Thereafter, the same operation as that described with reference to FIGS. 4 to 7 is repeated, and when a predetermined number of glass plates 17 and the sheet material 4 are laminated on the pallet 11, one operation is performed. The glass plate lamination operation on the pallet 11 is completed.

By performing the operation as described above, the sheet material 4 is securely held by the holding means 5 and 6, and the surface side of the glass plate 17 on the pallet 11 is avoided in a state where generation of wrinkles and the like is avoided. Therefore, the sheet material 4 is smoothly interposed between the glass plates 17 without any trouble.

In addition, when it becomes necessary to change the width direction dimension of the sheet | seat material 4 by the change of the magnitude | size etc. of the glass plate 17, after replacing | exchanging the original material roll 2, it is a new withdrawn from the original material roll 2. After the guide member 12 is moved in the width direction along the rail 18 of the second base portion 15 to a position corresponding to the width of the strip-shaped sheet base material 1, the above operation is repeated.
